LeakSan tests taking a very long time

[eigenraven]

Just looking at recent actions logs, it looks like there's a lot of 30s sleeps between tests that for some reason only happen when testing with the Leak santitizer enabled.

According to the docs the leak sanitizer should:

• Add no overhead.
• Be enabled by default with Address Sanitizer.

Do you know what could be happening then?

I have no idea, but if asan can already cover it we can probably just remove independent leaksan. The docs do say it is a much less tested/supported configuration.
